a .novel and improved means for braking mechanism for bringing the sleigh to a stop,

t this braking mechanism including a device for neutralizing the propeller.` vz

For further comprehension .of the invention, and of ,the objects and advantages thereof, reference will be had tothe following description and accompanying; ldrawings, and to the appended claims in whiolrA s The vane of each set whichis arranged the various novel features of the invention are more particularly set forth.' y 1 .1 of the drawings-is a side view 4of invention embodied therein. .f

along the line 3-3 0f Fig. 1, and illustrating the' shutter elementin closed position;

Fig. 4 is a similar view, but showing the shutter element in opened position. f

Fig. 5 is an edge view of the shutter eley ment in closed position.

' Fig. 6 is a detail view showing the Vyieldino' element in the shutter extending means.

eferring now to the drawings the reference numeral 10 indicates generally the body of the sleigh which is projected forward in the form of an engine hood 11 which is preferably of circular shape as seen in end view. These parts are carried in suitable side frames 12 mounted by ordinary leaf springs 13 on front and rear runners 14 and 15.

The front runners 14 may be mounted on knuckle elements 16 and are steered by` means of a wheel 18 on a shaft 19 on which is also fixed a cross-bar 20 connected by ropes 21 to opposite ends of a cross-bar 22 fixed to a T-shaped lever 23 pivoted as atv 24 to the frame of the sleigh. The ends of the cross-piece 23 of the lever are pivotally attached to the front runners as at 25. The

'move in opposite directions.

ropes 21 may be ledaround suitable pulleys 26 tothe ends of the cross-.bar 22,

.'lhe' sleigh isadapted tobe driven by an air propeller 30 ofk usual helical type and fixed on the sha-ft of the engine. (not shown).

vFor use whenjthe sleigh is to be stopped I provide behindthe propeller a fan-like shutter; element which is illustrated in detail in Figs. 3, 4 and 5.y This shutter element comprises a seriesl of triangular vanes 32 which have a common pivotal point at 33fupon the engine hood 11.l These vanes 32 are preferably made oftransparent material such as Celluloid* fixed in suitable frames.

movable sets, the respective vanes ofthe different sets having slot and pin connections 35' with one another which permit -of their being folded to` the position shown in Fig. 3 or extended as in Fig..'4.

to swing through vthe .greatest arc has fixed thereto a1 quadrantal geary 3.8,'these gear quadrants 38 meshing .with 4respective ones of a pair of .gears 39. one of which is mounted` onta stub shaft '540 and-the other on a rearwardly extended shaft 41. The gears 39 mesh also' with one another sothat upon shaft: 41 being rotated vthe quadrants 38 ywill These quadrants 38 are offset laterally to cleary one another as shown in Fig. 5, the gears 39 being also slightly offset to enable the quadrant engaging one gear to clear the other.

The `v anesr 32, are arranged in two yoppositely To rotate shaft 41y asmall pulley 43 is y mounted on the rear end thereof and is connected by a belt 44 with a large pulley 45 on a parallel stub shaft 46 mounted in suitable bearings. T he stub shaft 46 has also fixed thereto' a bevel gear 47' meshing with a like gear 48 on a transverse shaft 49. This transverse shaft 49 has fixed thereon a hand lever y50 which may be locked in adjusted position by the usual latch 51, engaging aV notched quadrant 52,

To work in co-operation withthe shutters just described I provide a series of brake ordrag arms 55 iiXed on a transverse shaft 56 toward the rear end of the sleigh these brake elements having toothed faces such asy 57 having a spiral curvature with respect to the shaft 56. `Fixed to shaft 56 is an arm 58 connected by a link 59 with a second arm 60, fixed to shaft 49.

In order to permit of the drag elements continuing their gripping position after the shutter element is extendedk pulley v is loosely mounted on shaft 46 and has a yieldine connection therewith by means of a rac ial spring 63 fixed atjone end to the shaft and projecting at opposite ends between a pair of pins 64 fixed to the pulley.

Upon operation of lever 50, to bring the sleigh to a stop, motion is transmitted through bevel gears 48 and 47, rope 44, shaft 41, gears 39 and gear 'quadrants `38`to the vanes 32, Acausing the 'same to spread to the position shown in Fig. 3,`the end vanes being anchored-to the engine hood llas at `32', as will be understood. The pull of the propeller 30 is thus neutralized. As the vanes reach their extended positions the drag elements 55 engage thesnow or ice, and by reason of their-spiral gripping lfaces 57, act to raise the runners so the weight of the sleigh is borne onthese4 drag elements which quickly stop the sleigh.

With my `improved. device the necessity of stopping'the propeller 30 every time -the sleigh is to bestopped is obviated, wh-ile a slow or a quick stop can be made as desired.

hHaving thus described my invention what l 4claim as new and desire to protect 'by Letters Patent of the' United States is as follows: f y

l. In a sleigh, an air propeller, a normally collapsed fan-like yshutter element mounted behind said propeller, vand means for extending said shutter element.

2; ln a sleigh, an air propeller, anornially collapsed fan-like shutter element mounted' behind --saidpropellen and means for extending` said vshutter element, said shutter element comprising two series of vanes radiating from a cpmmon point the respective vanes of each series having slot and pin connections with one another.

3. In a sleigh, an air propeller, a normally collapsed fan-like shutter element mounted behind said propeller, and means `for extending said shutter element, said shutter.` element comprising two series of vanes radiating from a common point the respective vanes of each series having slot and pin connections with one another, said shutter extending means comprising a pair 'of gear segments each `lixed to a vane of the respective series, a parir ofygears mesh-ing with eachother andfwith the respective segments, and means for rotating one ofi-said gears. f

4." ln a sleigh, anrair propeller, `anormally collapsed fan-like shutter element mounted behind said propeller, a'fdragy element adapted to fengage the surface on which thesleighL is traveling, and a common ter and'dragelements, and a hand leveren said shaft.

vl'n testimony whereof? l'rhave aiiixed my signature.
